Explanation:
Crystallization is a separation technique used to obtain pure crystals of a substance from an impure mixture of solid substances.
The impure solid is dissolved in an appropriate hot solvent. This hot solvent is able to effectively dissolve the solid. However, as the solution is allowed to cool, the pure solid separates out of the solution as crystals.
The solid is now filtered to obtain the pure solid. The solid is also washed and dried to remove any solvent contaminant.
Si un gaz exerce une pression de 2,00 atm lorsque 20 bouffées de particules sont présentes alors pour 4,50 atm il faut 45 bouffées car 20 bouffées = 2,00 atm donc 2*20=40 +0,5 =4,50
Answer:
The ribosome contains three grooves which are sites for the tRNA. The first codon is AUG, which is called a "start codon". ... So, the tRNA that has the anti-codon sequence of UAC carrying the amino acid Met bonds to the mRNA codon. Another tRNA bonds to the next codon in the next groove with the next amino acid
